Product Application
Timken's Mill Grease can be applied from ambient temperatures of -10° F to +400° F (-23° C to +204° C) depending on lubrication system design and method of application. Mill Grease has an operating range of -40° F to +400° F (-40° C to +204° C) once in the application (depending on frequency of application).
CAUTION: Follow equipment manufacturer’s recommendations concerning lubrication frequencies. Failure to follow correct lubrication practices can result in premature equipment failure.
Compatibility of Grease
Mill Grease is generally compatible with calcium, calcium 12-OH stearate, calcium complex, calcium sulfonate, lithium, lithium-complex and polyurea-thickened greases. Timken recommends that all grease be removed from the application prior to changing greases. Then the lubrication interval is reduced by half for the first lubrication cycle before resuming the normal lubrication interval.
Handling and Storage
Store in a dry area away from heat and open flame. See Material Safety Data Sheet (MSDS) for more information.
Shipping and Disposal Information
Follow governmental regulations pertaining to the shipping and disposal of this product. Do not reuse container. See MSDS sheet for more information.
